Navigating at night using nothing but maps, compass, altitude and speed indicator is pretty difficult. Especially when the hostile territory you are flying over is forcing everyone to keep their curtains closed and minimize light leaks.
I’ve done some night flying by dead reckoning. I had the benefit of meteorologists in the territory I was flying over, so I had pretty good winds aloft data. That makes a DIFFERENCE.

Why didn’t they just use the GPS?
time travel hadn’t been invented yet.
Because the Earth is flat, they would’ve had to have used FPS
